Daughter in law will never be a real daughter to her mother-in-law because mother-in-law is never the real mother. No matter how good both the individuals are, but there is always a thin line between mother-in-law and daughter-in-law. The Mother brings up her child, has seen the child grow up through different stages of his life till now, and most importantly she has seen him since his childhood, since he was a newborn, who could not do anything on his own. So that image of the child never leaves the Mother, So for her He will always be her baby no matter how old he grows. Now coming to the point of Daughter-in-law, she meets this girl when the girl is in her adulthood, she can’t possibly have the same feelings as she had for that newborn whom she has seen grow infront of her eyes. So for a Mother-in-Law, a Daughter-in-Law can never be a Daughter, cause she has not met this individual during her growing years. So it will never be the feeling of a young child whom she has seen grow. Instead she enters her life when she is an adult. never try to be a daughter to your Mother-in-law, try to be her friend. Friendship improves all kind of relationships. If you can be friends with her and have the understanding it cannot be possible for her to see you in the same way she sees her son. You would be in a better place to engage in a better understanding of your relationship .
